According to Wikipedia:
"Gridlee is a 1983 arcade game produced by Videa. Only one Gridlee cabinet is known to exist."
According to klov.com
(Killer List Of Videogames):
"Only one actual working Gridlee machine was ever produced and it is currently owned by Dale Luck. To preserve this piece of gaming history, the three co-founders of Videa (Howard Delman, Ed Rotberg, and Roger Hector) have provided images of the game's PROMs free for noncommercial use."
